Oil derricks? Why can't I build them?

[Red Ninja]

I've gone to the Resources tab -> Petrolium tab -> Facility Controls and looked for Oil Derrick or Oil Platform or anything to indicate a sea-based oil extraction facilty. I only see 3 available - "Oil - Gas Field", "Early Oil - Coal Synth", and "Oil - Coal Synth". The country I'm playing (Mozambique) starts with a sea platform and single oil derrick so I tried right clicking on it and selecting "Build" but I can't find the "Oil Derrick" in any of the "Build" lists. According to the manual, the Oil Derrick doesn't require any particular tech.

Where do I go in the UI to build an oil derrick? I searched Google and these forums and no one has asked this question, so I must be missing something.

What year did you start?

Edit: I tested it and I have same issue.

Full disclosure, I have not built any Ocean Complexes in SRU. Not sure if there is a prerequisite tech. The existing platform could be left over from when they where a colony.

It seems that for SR1936, tech 1736 Underwater Petroleum Extraction which needs 1735 Mobile Steel Barges. Both are technology category in research.

I would also note that Mozambique has no access to offshore oil, so may not be worth the research unless you've managed some impressive conquests.

Starting as Denmark in GC2020, I was able to build an additional oil derrick at 844, 125 to confirm they are working when you have the techs.

In a Sandbox 2020 World start, Mozambique starts game with one Oceanic Complex (X1080 Y513) and one Oil Platform. If the oil hex follows all other conventions, one should be able to build a second Oil Platform on the hex.

I guess if those two techs you typed above are researched, he should be able to build a second Platform.

@chrisahl, Mozambique starts with an ocean complex and oil derrick in sandbox 2017. Thanks for the information on the Technologies needed to build the Derrick. The existing one must have been left over from a previous colonization from a European power. I guess I'm going to have to figure out what path I need to take to get to that technology. Since neither of those Technologies appears in my technology category, there must be prereqs for those that I don't have yet. This is where a tech tree would come in handy LOL

In the 2017 Trump Rising Sandbox start, Mozambique has Mobile Steel Barges(1933 tech), as one of the 19 Technologies which may be researched. Once it is researched, it unlocks Underwater Petroleum Extraction (1938 tech).

Must've missed it. Not the first time I missed something in this game. So many menus lol. Thanks so much guys
